Java使用循环从数组中删除重复项 [英] Java remove duplicates from array using loops

问题描述

这是我当前的尝试，从包含整数的数组中删除重复项，但这没有任何结果。它只是什么都不打印。任何帮助将不胜感激。

This is my current attempt to remove duplicates from an array holding integers, but this does not give me any results. It simply prints out nothing. Any help would be greatly appreciated.

    public static void duplicate(int numbers[], int size)
    {
      for (int i = 0; i < size; i++){
        boolean duplicate = false;
        int b = 0;
        while (b < i){
          if (numbers[i] == numbers[b])
             duplicate = true;
          b++;}
        if (duplicate = false)
          System.out.print(numbers[i] + " ");}
    } 

推荐答案

尝试一下：

public static void duplicate(int numbers[], int size)
{
  for (int i = 0; i < size; i++){
    boolean duplicate = false;
    int b = 0;
    while (b < i){
      if (numbers[i] == numbers[b])
         duplicate = true;
      b++;}
    if (duplicate == false)
      System.out.print(numbers[i] + " ");}
} 

您需要使用 == 而不是 = 在您的if语句中。

You need to use == not = in your if statement.
